Very nice aqua glass bushing marked R 5050 -- measures 3 1/2 X 4 1/8" -- great shape with just a tiny ping on the back -- $110 plus actual shipping

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
